IMPROVEMENT IN THREAD-GUARD SUPPORTS FOR RING-SPINNING FRAMES.

Specification forming part of Letters Patent No. 202,420, dated April16, 1878 application filed August 18, 1877.

To all whom it may concern:

Be it known that I, JAMEs DOYLE, of Lowell, Massachusetts, have inventedan Improvement in Thread-Guard Supports for Ring- Spinning Frames, ofwhich the following is a specification:

The invention has for its object an improved mode of holding the guardsbetween adjust able spindles, so that they can prevent the yarn of twoadjacent spindle-bobbins from coming in contact; also, of avoiding theirattachment to the ring-rail, that produces so much extra weight, and-isso objectionable to ring-spinners, and of removing all obstruction fromthose who piece the threads and operate the frame.

The invention consists in my particular means for holding the guards ina pendent position and regulating them by means of a weighted arm andstop-bar.

Figure 1 of drawing is a front elevation. Fig. 2 is a vertical sectionthrough line 00 as of Fig. 1.

A represents the ordinary frame; a, the rings, and B the rin g-rail. Ois a bar on frame A, and from it are hung the hangers D D, provided attheir lower ends with a shaft, E, that is free to oscillate in rear ofring-rail nearly the full length of the machine, andhas a loaded arm, F,as well as a stoparm, G. J are looped guards rigidly attached to shaftE, and on the forward movement of the oscillation of this shaft they arebrought between the rings a.

I am aware that guards have been used for this purpose; but beingattached to the ringrails by the same screws that hold the rings inplace, and having their rock-shaft in line with the screws, it wasimpossible to remove a worn-out ring without first removing a section ofthe shaft.

The guards have also been heretofore arranged to run above thethread-guide when the ring-rail is at the top of bobbin, thusobstructing those who piece the threads.

My guards follow the ring-rail down to a point about half-way betweenthe top and bottom of bobbin, remaining in a horizontal position bymeans of the stop-arms until the rail goes to the bottom of bobbin andreturns up to the guard; also, whenever the ring-rail is to be adjustedfor repair or correcting any defeet in the lifting-rods, the ring-railcan be laid on the thread-boards without breaking the threads.

What I claim as new and of my invention 1s In ring-spinning machines,theguards J, in combination with a pivoted hanging shaft, provided with aweight and stop to regulate the position of said guards, as shown anddescribed.

JAMES DOYLE.
